Bear and Armor Vault both make great safes in Oklahoma. The steel thickness is superior to safes that are much more expensive. However, i do believe they start at a much higher price than the stated budget.
If you go the Job Box route, please buy the absolutely best locks you can find that will fit, probably from a lock smith. Get them keyed the same for convenience. The two locks could run $100, just know that will be the week point in the system. However, they are 10 times better than a $500 Cannon, see the video "Security on Sale". I have seen one of these cheap ((<$500) safes opened with a $15 pry bar in under a minute. That's what $500 gets you. Better off hiding them in the attic.
